In general, I agree that ETH is a profitable asset for investing, but I think that Vitalik and his team should work on their product for a long time in order to reduce the amount of commissions, which is one of the most expensive today.
The year really promises to be profitable. If we rely on the recent events that happened with the Dogecoin, then we can only guess what surprises await us in the near future.
Not to mention the two strongest leaders. I do not think that the history of 2017 will repeat itself, but I have no doubts about the success of some crypto projects.
